Heat is involved in many processes in the food industry: drying, dissolving, centrifugation, extraction, cleaning, washing, and cooling. Heat generation encompasses nearly all processes. This review first presents two representative case studies in order to identify which processes rely on the major energy consumption and greenhouse gas (GHG) emissions. Energy-saving and decarbonating potential solutions are explored through a thorough review of technologies employed in refrigeration, heat generation, waste heat recovery, and thermal energy storage. Information from industrial plants is collected to show their performance under real conditions. The replacement of high-GWP (global warming potential) refrigerants by natural fluids in the refrigeration sector acts to lower GHG emissions. Being the greatest consumers, the heat generation technologies are compared using the levelized cost of heat (LCOH). This analysis shows that absorption heat transformers and high-temperature heat pumps are the most interesting technologies from the economic and decarbonation points of view, while waste heat recovery technologies present the shortest payback periods. In all sectors, energy efficiency improvements on components, storage technologies, polygeneration systems, the concept of smart industry, and the penetration of renewable energy sources appear as valuable pathways.

“…15 There are also reported studies on the transport of ammonia and the cleaning of process pipelines in various ways using inert gases and the thermodynamic behaviour of ammonia. [16][17][18] Considering the volume changes that may occur in the lines where ammonia is transported, as well as the environmental risks involved in the transportation of ammonia are important issues studied. 19,20 In the literature, the number of loops used to reduce the problems caused by sudden volume changes during the ammonia transfer and their exergy analysis have not been reported on an industrial scale.…”
